Abstract (en)
[origin: CA2939182A1] The application relates to a method for producing a microneedle system (10), wherein from a board (21) is produced a web grating (41) which has a plurality of grating nodes (42) defined by in each case three apertures (22) and which has web grating wedges (51), and to a microneedle system comprising a board and a plurality of openings (31) delimited circumferentially by a web grating, wherein there is arranged at each opening at least one web grating wedge having a needle-shaped tip (56) which projects from the board and which is oriented at least approximately normal to the board. Web grating wedges having needle-shaped tips protrude into each aperture from at least three different directions. In order to produce openings, at least all the web grating wedges which protrude into an aperture are bent by means of a punch (72) and the needle-shaped tips thereof are oriented normal to the plane of the web grating. At least two web grating wedges are arranged at each opening, the bending lines of which are oriented non-parallel to one another. By virtue of the present application, the operational safety of a microneedle system is increased.
